ZERO Math Puzzles电脑版

This is a purely mathematical puzzle game in which you drag the brown squares through other number squares and the goal is to make the number in the brown squares zero. Each number of squares can only be passed once, and "use" cannot be repeated. If there is a square that can be repeated, the number in the upper right corner of the box will appear as a reminder. If "2" appears, it can pass 2 times, and so on.. Enjoy!
